git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm
Pull more MM updates from Andrew Morton:
- "mm: make VMA flag semantics explicit, eliminate VM_SPECIAL" (Lorenzo
Stoakes):
Replace VM_SPECIAL with helpers describing mapping ownership and
behavior. Enforce the mmap flag rules and convert affected drivers,
removing ambiguous tests shared by driver mappings and ordinary
memory.
- "support kselftest on nommu platform" (Hajime Tazaki):
Add opt-in mmap and mremap tests for NOMMU systems. Teach the runner
to avoid its fork-dependent timeout command and document the build
and runtime requirements.
- "mm/collapse: separate a collapse from its callers" (Kiryl
Shutsemau):
Separate huge-page collapse from caller policy. Replace khugepaged
identity checks with explicit permissions, and separate scanning from
collapse with the mmap_lock drop in one place.
- "mm: implement and use vma_has_anon_rmap(), silence KCSAN" (Lorenzo
Stoakes):
Provide a common helper for testing whether a VMA has anonymous
reverse mappings. Document the locking rules, annotate intentional
concurrent reads for KCSAN, and convert the core MM callers.
- "mm/sparse: remove SECTION_MARKED_PRESENT and further cleanups"
(David Hildenbrand):
Remove SECTION_MARKED_PRESENT in favor of the early-section flag.
Simplify sparse memory initialization, section metadata handling and
related PFN validity checks.
- "sh: remove NUMA and SPARSEMEM support" (Mike Rapoport):
Remove SuperH NUMA and SPARSEMEM support. The extra memory banks have
been unusable since the NO_BOOTMEM conversion, leaving only the code
and data overhead.
- "mm: Unify device DAX and HugeTLB vmemmap population paths" (Muchun
Song):
Unify the generic device DAX and HugeTLB vmemmap population paths and
shared tail-page handling. Remove the duplicate DAX machinery while
retaining the powerpc radix implementation.
- "kselftest: mm: fix some failure of split_huge_page_test" (Yeoreum
Yun):
Fix huge-page split tests racing with khugepaged recollapse. Use
pagemap and page flags instead of VMA-boundary assumptions which fail
when glibc has already enabled THP.
- "memcg: move memcgid refcount to objcg to unpin dying memcgs"
(Bingfang Guo):
Let dying memcgs be freed while swapped-out shmem still holds their
IDs. Move ID references to reparentable objcgs, with the necessary
swap accounting and RCU lifetime changes.
- "mm/truncate: fix data loss when truncating straddling large folios"
(Zhang Yi):
Preserve out-of-range data when truncating straddling large folios.
Fix a lookup race and split-failure handling, and handle minimum
folio orders for the forthcoming ext4 iomap buffered I/O path.
- "mm/damon: introduce damos quota goal target metric complement flag"
(SJ Park):
Let DAMOS quota goals use a metric's complement, so utilization can
also express free-memory goals without adding separate metrics. Add
the sysfs interface, documentation and tests.
- "arm64/mm: Standardize printing for pgtable entries" (Anshuman
Khandual):
Use the generic formatter for arm64 page-table entries, ready for
future wider entries. Move the safe-PTE-update check out of the
header to avoid an include cycle.
- "mm: kmsan: fix iounmap metadata teardown" (Dima Koziuk):
Fix KMSAN metadata leaks on iounmap and failed ioremap allocations.
Free backing pages before removing their mappings, and share the
teardown with partial-allocation cleanup.
- "mm/damon/core: preserve quota state when constructing schemes" (Karl
Mehltretter):
Preserve running DAMOS quota state while validating parameter
updates. Even rejected updates could reset accounting and exceed the
quota window; add tests for both accepted and rejected updates.
- "mm/vmalloc: fix vmalloc_dump_obj VA lookup" (Ye Liu):
Fix vmalloc_dump_obj() lookups for last-page addresses and
allocations spanning vmap zones. These allocations were being missed
in diagnostic output.
- "mm: various (urgent?) fixes" (David Hildenbrand):
Fix mmap charge leaks and hugetlb use-after-free, wrong-address
unmapping, stuck locks and endless faults. Also preserve reservations
on failed mremap and handle stale userfaultfd bits.
- "maple_tree: fix maple_range_64 crashes in RCU mode" (Dimitris
Charisis):
Fix pointer and metadata confusion during RCU destruction of
maple_range_64 nodes, avoiding double frees and invalid accesses. Add
a regression test; no in-tree user currently uses this combination.
- "mm: fix hugetlb NR_HUGETLB accounting on folio migration" (Hongfu
Li):
Fix hugetlb migration and preallocation accounting so /proc/vmstat
retains the correct count and memory.numa_stat follows the folio to
its new node.
- "mm/damon: fix a minor bug, clean code, and add a test" (SJ Park):
Fix 32-bit DAMON age overflow which made old regions look young.
Share hugetlb folio acquisition code and add a regression test for
the previously fixed last-region skipping bug.
- "mm/damon/core: cleanup code, reduce stack usage, and add kunit" (SJ
Park):
Reduce kdamond stack usage and remove unused enums. Add deterministic
PSI quota-goal tests which do not depend on the machine's current
memory pressure.
- "mm/damon: fix the temporal goal tuner's size quota conversion"
(Donggeun Yoo):
Bound the temporal tuner's quota conversion to prevent overflow and
zero effective quotas, which could stop schemes making progress. Add
boundary tests.
- "Don't use GFP_DMA when calling dma_alloc_coherent" (Baoquan He):
Remove redundant GFP_DMA flags from coherent DMA allocation calls.
The DMA API already selects the zone from device limits and ignores
the caller's flag.
- "kselftest: mm: fix intermittent failure khugepaged test" (Yeoreum
Yun):
Propagate child-process failures in the khugepaged tests and prevent
background collapse from racing their checks. This removes false
passes and intermittent failures.
- "MAINTAINERS: cover all hugetlb headers under HUGETLB SUBSYSTEM"
(Enze Li):
Cover all hugetlb headers in MAINTAINERS so get_maintainer.pl finds
the right maintainers. Also label the closing hugetlb_cgroup.h
include guard.
Summary of the 65 singletons in this merge:
The singletons include a few worthwhile performance fixes. Avoiding
unnecessary reverse-map tree updates gave a reported 15.9% improvement
in UnixBench's execl test on a 192-core x86 system. A reclaim retry
fix stops defrag_mode from spinning under memory.low protection; a
reported file-creation stress test ran 5.7 times faster, with far less
memory pressure. Narrower hugetlb invalidations also spare KVM guests
needless refaults: the reported Redis-in-VM P99 QPS penalty while
punching holes fell from 7.09% to 1.45%.
Several fixes prevent lost data or corrupted memory. Lazyfree
huge-page races with mremap()/munmap() could lose data or access freed
memory, and MADV_COLD could lose a concurrent write's dirty bit.
Another fix prevents stale migration entries from outliving large
folios. On filesystems with blocks smaller than a page, extending a
file by 4 GiB or more could expose bytes written past the old EOF
through mmap instead of zeroes. That is fixed, along with
use-after-free races in PAGEMAP_SCAN during process exit and in
memory-cgroup accounting on PREEMPT_RT kernels.
Other fixes stop UFFDIO_MOVE spinning forever on pinned large folios,
which could wedge other memory operations, and stop mremap() leaking
commit charges until allocations fail under strict overcommit. A
further fix keeps userfaultfd tracking intact on neighboring mappings.
NUMA binding no longer prevents long-term pins when the chosen node
has only movable memory, fixing QEMU/VFIO startup and io_uring buffer
registration failures. MGLRU also gets a fix for early-boot crashes
with memory cgroups disabled at boot, notably in small crash kernels.

Pull f2fs updates from Jaegeuk Kim:
"In this round, key enhancements focus on introducing a dedicated
metadata cache infrastructure and dynamically parameterizing on-disk
block layouts and geometry macros.
Moving meta, node, and compress blocks out of the VFS page cache
removes the page == block size assumption for metadata, which along
with dynamic block layout descriptions paves the way for large folio
and page != block support in the future.
We also opt in to multigrain timestamps, add bio entry-count
throttling for asynchronous write_end_io completion, and expose the
resizable_tail feature via sysfs.
Alongside these features, critical bug fixes resolve race conditions
across compression, mmap write faults, checkpoint/shutdown, and
filesystem freeze, prevent write bio splitting and GC holes on
sequential zoned devices, and strengthen on-disk sanity checks for
SIT/NAT bitmaps, read-only curseg entries, and device aliasing.
Additional stability patches address online resize, roll-forward
recovery, atomic file operations, quota handling, and dirty inode
syncing livelocks.
Enhancements:
- implement dedicated metadata cache for meta, node, and compress
blocks to decouple metadata from page cache for large folio and
page != block support
- dynamically describe SIT, NAT, orphan, dentry, node, and xattr
block layouts and parameterize block/sector/node conversion macros
- opt in to multigrain timestamps
- introduce max_atc_write_bio_entry_cnt sysfs node
- expose resizable_tail feature via sysfs
- avoid unnecessary reads in f2fs_update_meta_block()
Bug fixes:
- compress: force out-place update for all writes, allow pinning
empty compressed files, and fix truncate/writeback and cache
population races
- zone: avoid bio split and GC target block grab failure on
sequential zones
- quota: convert inline quota files on quotaon, fix flush failure
during freeze, and restore empty string mount options
- atomic/mmap: disallow mmap write and data-modifying fallocate on
atomic files, avoid truncate_inode_pages_final() on live inodes,
and fix races in f2fs_vm_page_mkwrite()
- resize/alias: refresh pinned allocation boundary and flush SIT
journal during resize, and drop pending discards before reserving
device alias
- sanity check: bound SIT/NAT bitmaps by checkpoint pack, check all
cur_*_segno[] on readonly images, and validate multi-device on
device alias
- recovery/cp: release removed xattr node in roll-forward recovery,
invalidate curseg on change_curseg() failure, and return -EIO for
lost inode block after cp_error
- fix livelock in syncing dirty inodes and preserve APPEND/UPDATE ino
entries
- use bio_in_atomic() in f2fs_{read,write}_end_io()
- fix 32-bit shift truncation in mount option bitmasks and defragment
range
And a number of minor bug fixes"

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Set supported_speeds in set_pcie_port_type() so sparc64 and
powerpc, which call it via of_create_pci_dev() instead of the usual
pci_setup_device(), correctly set the supported PCIe link speeds
(Stian Halseth)
- When pcie_set_mps() changes MPS, update the value in the saved
state so a subsequent restore doesn't restore an invalid value
(Niklas Cassel)
- Skip Target Speed quirk on clamped ports with no link (Maciej W.
Rozycki)
Driver binding:
- Assume control of portdrv-related features only when portdrv is
enabled, since we can't use them without portdrv (Kuppuswamy
Sathyanarayanan)
- Centralize feature ownership checking so code only needs to check
'host->native_X' and doesn't need to also check 'pcie_ports_native'
(Kuppuswamy Sathyanarayanan)
Error handling:
- Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
mention a device that no longer exists (Priyank Rathod)
- Fix aer_process_err_devices() leak when a device is recorded as an
error source purely by being mentioned in the Root Port Error
Source and the device is inaccessible or logged only masked errors
(Priyank Rathod)
ASPM:
- Disable ASPM when drivers request that, even if the OS doesn't own
ASPM; otherwise drivers do it on their own, which is worse (Ilpo
Järvinen)
Power management:
- Align hibernate poweroff flow with suspend flow for bridges so they
can be powered down at hibernate as they are for suspend (Mario
Limonciello)
- Restore BARs after powering up during enumeration to fix a
regression on devices that don't preserve state in D3hot (Keng-Yu
Lin)
- Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting
them in D3hot takes down the whole switch (Imre Kaloz)
Power control:
- Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
Elder)
- Add DT documentation and pwrctrl driver support for TC9563 embedded
GPIO controller (Lorenzo Bianconi)
- Switch the tc9563 per-port reset to use the GPIO descriptor API
instead of direct regmap accesses (Lorenzo Bianconi)
- Only destroy devices created by pwrctrl core, so that when removing
a PCIe controller driver that uses pwrctrl, we don't remove devices
populated by another mechanism (Shawn Lin)
- Power off child devices on power-on failure (Lorenzo Bianconi)
PCIe native device hotplug:
- Make the 'pciehp_poll_mode' parameter read-only to prevent changes
via sysfs, which can cause errors when unbinding (Runyu Xiao)
Virtualization:
- Read SR-IOV VF Revision ID and Subsystem ID from VF instead of
assuming they're the same as VF 0; they may differ (Logan Odell)
- Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)
Peer-to-peer DMA:
- Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
bridges to allowlist (LeoLiu-oc)
- Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)
- Add Intel Haswell client host bridge to allowlist (Scott Lee)
- Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)
- Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
unmapping a BAR if registering another fails and (b) use after free
of p2p_pgmap (Leon Romanovsky)
- Wait for RCU readers before freeing state to avoid use-after-free
of pdev->p2pdma (Leon Romanovsky)
- Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
Romanovsky)
- Safely terminate ACS redirect lists to avoid out-of-bounds access
to the buffer (Leon Romanovsky)
- Silence 'Host bridge not in P2PDMA whitelist' warnings unless
caller, e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon
Romanovsky)
Sysfs:
- Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes
when Device Name _DSM fails, not -1, which is interpreted as -EPERM
(Krzysztof Wilczyński)
- Return valid sysfs 'acpi_index' attribute even if the Device Name
_DSM returned an invalid 'label' (Krzysztof Wilczyński)
- Expose sysfs 'acpi_index' and 'label' based on whether the Device
Name _DSM returns valid data, not merely whether the _DSM is
implemented (Krzysztof Wilczyński)
- Avoid out-of-bounds reads of the label returned by the Device Name
_DSM, which is in UTF-16 characters, not bytes (Krzysztof
Wilczyński)
- Reject unaligned resource I/O port accesses, which can oops on
arm64 (Deepanshu Kartikey)
Endpoint framework:
- Pass the correct physical and virtual endpoint function numbers
when setting translation of inbound memory windows (Koichiro Den)
- Make embedded doorbell IRQ non-shared, since currently only the
first EPF can allocate doorbells (Koichiro Den)
- MSI doorbells currently target the first EPF attached to an EPC;
let other EPFs try the embedded doorbell instead of failing when
they can't use the MSI doorbell (Koichiro Den)
- Serialize scan of vNTB virtual PCI bus with other PCI topology
changes (Koichiro Den)
- Manage vNTB lifetimes to avoid leaking virtual devices and buses
and allow removal (Koichiro Den)
- Track vNTB link state from both sides so both see the same
effective link state (Koichiro Den)
- Configure vNTB MSI-X when supported to avoid IOMMU faults and
failure to deliver doorbell interrupts on RC (Koichiro Den)
APM X-Gene PCIe controller driver:
- Use devm for clocks so they're automatically disabled, unprepared,
and released if errors happen during probe (Yuho Choi)
ASPEED PCIe controller driver:
- Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
Zhenlong)
Broadcom iProc PCIe controller driver:
- Expose devm_pci_alloc_host_bridge_release() so drivers can share a
devm release function even if they don't need the device tree
parsing done by devm_pci_alloc_host_bridge() (Bjorn Helgaas)
- Request only the memory window from BCMA Enumeration ROM and warn
if it doesn't match the one in DT, which fixes an iproc-bcma probe
failure (Semih Baskan)
Broadcom STB PCIe controller driver:
- Replace bool properties for each SoC configuration with a u32
bitvector and a BFLAG() helper (Jim Quinlan)
- Use a similar BQUIRK() helper to test various SoC quirks (Jim
Quinlan)
Cadence PCIe controller driver:
- Remove device links to PHY, which are redundant because the PHY
core itself adds them (Vladimir Oltean)
- Return error (not success) from cdns_plat_pcie_probe() if
pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir
Oltean)
- Correct the driver data pointer usage; previously .probe() stored
'struct cdns_plat_pcie *', but .shutdown() used the pointer as
'struct cdns_pcie *', resulting in accessing garbage (Linmao Li)
ESWIN PCIe controller driver:
- Publish the platform driver MODULE_DEVICE_TABLE so the driver can
be autoloaded when built as a module (Pengpeng Hou)
Freescale i.MX6 PCIe controller driver:
- Fix resource and pwrctrl device leaks .probe() (Zhijian Han)
- Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
default 120 to 140 (Richard Zhu)
- Use dev_err_probe() in host init error path to silence
-EPROBE_DEFER messages (Alexander Stein)
- Avoid dereferencing NULL clock names when 'clocks' includes more
phandles than 'clock-names' has names (Rudi Heitbaum)
- Add suspend_poweroff flag so platforms like i.MX that power off RC
controllers during suspend can enter L2 so endpoints can get
PME_Turn_Off notifications before power loss (Richard Zhu)
Freescale Layerscape PCIe controller driver:
- Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
controllers on LX2160A (Vincent Jardin)
Intel VMD host bridge driver:
- Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
before write has completed, resulting in an nvme 30 second stall
before a QID timeout and possibly other similar problems (Rickey
Bartlett)
- Flush DMA writes before handling MSI on Arrow Lake (Vladimir
Nedoshivin)
Marvell Aardvark PCIe controller driver:
- Disable PHY on probe failures (Myeonghun Pak)
Marvell MVEBU PCIe controller driver:
- Refcount child OF nodes during .probe() to make a concurrent OF
overlay removal safe (Krzysztof Kozlowski)
MediaTek PCIe controller driver:
- Find INTx DT property by 'interrupt-controller' name instead of
assuming it's the first child node (Zhengping Zhang)
MediaTek PCIe Gen3 controller driver:
- Fix a 64-bit type truncation in mtk_pcie_set_trans_table() to avoid
issues with windows above or larger than 4GB (Sreeraj S Kurup)
NVIDIA Tegra264 PCIe controller driver:
- Fix the Link Capabilities offset so we read the correct register
(Bjorn Helgaas)
Qualcomm PCIe controller driver:
- Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
resets used by downstream devices like USB controllers (Christopher
Obbard)
- Block accesses to downstream devices on link down to reduce a storm
of Completion Timeout AER interrupts (Qiang Yu)
- Skip system suspend/resume for firmware-managed PCIe, where
firmware manages clocks, regulators, resets, etc (Mrinmay Sarkar)
- Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
(Manivannan Sadhasivam)
- Deinitialize endpoint on remove (Guangshuo Li)
- Treat Root Port error recovery as successful even if link doesn't
come up after reset because the device was hot-unplugged (Konrad
Dybcio)
- Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
indicating an external MSI controller (Ayiluri Naga Rashmi)
Renesas R-Car PCIe controller driver:
- Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
Vasut)

Pull MM updates from Andrew Morton:
- "selftests/mm: improve khugepaged coverage" (Kiryl Shutsemau):
Give khugepaged a proper workout. Extend the tests to all supported
mTHP orders, check exactly which windows collapsed, and make scan
completion deterministic. Race collapse against faults, pinning, fork
and remap; verify that the contents survive.
Add coverage for whole-page-table zaps and memory pressure too.
- "selftests/mm: separate GUP microbenchmarking from functional testing"
(Sarthak Sharma):
Untangle GUP benchmarking from correctness testing. Move the
benchmark into tools/mm, add a standalone harness-based GUP selftest,
and move shared helpers into tools/lib/mm. Give each tool one job
instead of mixing timing measurements with correctness checks.
Cover the mapping, pinning and batch-size combinations explicitly.
- "mm: Switch device DAX to section-based vmemmap optimization" (Muchun
Song):
Apply section-based vmemmap optimization to device DAX. Rework the
backing metadata layout to save memory while preserving the handling
of device memory hotplug and its different alignment and lifetime
requirements.
- "mm: Introduce section-based vmemmap optimization for HugeTLB"
(Muchun Song):
Cut the memory consumed by HugeTLB's struct page array with
section-based vmemmap optimization. Arrange the metadata so large
huge pages need fewer backing pages, while keeping initialization,
teardown and the various hugepage configurations straight.
- "mm/huge_memory: clean up and decouple the anon and file split
helpers" (Kairui Song):
Separate anonymous and file-backed folio splitting, which have rather
different locking and bookkeeping requirements. Move the work into
separate helpers, drop dead checks and tidy swap-cache handling. Fix
error paths, including one that could leave a folio frozen.
Keep the swap cache cases separate from file-cache splitting.
- "mm: Unconditional per-VMA locks and cleanups" (Dave Hansen):
Make per-VMA locking unconditional and clean up the old conditional
code around it. This removes configuration-dependent plumbing and
lets callers depend on one locking model rather than carrying both
cases along.
- "memcg: remove the v1 soft limit" (Shakeel Butt):
Remove the old cgroup v1 memory soft-limit machinery. This has long
since been superseded by the newer memory-control interfaces; hauling
around a separate reclaim scheme for it no longer buys us much.
- "read proc/pid/smaps_rollup under per-vma lock" (Suren Baghdasaryan):
Read /proc/PID/smaps_rollup using per-VMA locks where possible,
rather than holding mmap_lock across the entire walk. Retain the
contention fallback and add tearing tests. This considerably reduces
latency when another thread is busy changing its mappings.
- "mm/damon: introduce data access-as-a-data attribute" (SJ Park):
Teach DAMON to expose memory access observations as data attributes,
making them available to the probe and filtering machinery. Extend
the interfaces, documentation and tests so the new information can be
used rather than merely collected.
- "Remove PG_private by using page/folio->private checks instead" (Zi
Yan):
Get rid of PG_private and use the folio's private pointer to say
whether private data is attached. Convert the filesystem users,
including erofs, f2fs and md, and clean up the old accessors and
flags. There are a few special cases, notably swapcache and hugetlb,
which need explicit care.
- "mm: make userland page table freeing RCU-safe" (Lorenzo Stoakes):
Make freeing userspace page tables safe against RCU readers. Sort out
the page-table lifetime and locking rules so walkers cannot stumble
over freed tables while mappings are being torn down.
- "make unused huge shrinker memcg aware" (Qi Zheng):
Make shmem's unused-huge-folio shrinker aware of memory cgroups, so
reclaim can find those folios under the right memcg. Wire up the
per-memcg tracking and its lifetime rules, and give the shrinklist
its own lockdep class to avoid spurious dependency reports.
- "mm: Drop pxd_ERROR()" (Anshuman Khandual):
Remove the old pxd_ERROR() page-table checks and their
architecture-specific baggage. Simplify the common page-table
interfaces and callers now that these checks no longer serve a
useful purpose.
- "memcg: group struct fields by access pattern" (Shakeel Butt):
Rearrange memcg's hot and cold fields according to how they're
actually accessed. Keep frequently updated counters and their
neighboring state from fighting over cachelines and reduce needless
cacheline traffic.
- "mm/damon/core: fix the size charged for a filter-trimmed region"
(Donggeun Yoo):
Fix DAMOS quota accounting when a filter trims a monitoring region.
Charge only the part left after filtering, not the original region,
and add KUnit coverage. Previously the excluded memory could eat into
the quota and make schemes run more slowly than requested.
- "mm/damon: add kunit and selftests for probes and probe weights" (SJ
Park):
Add more tests for DAMON probes and their weights, including
validation and the results reported to userspace. This is mostly
about catching regressions in the newer probe infrastructure before
they become harder to diagnose.
- "mm: memcontrol: constify the read side of the read side of the memcg
API" (Tal Zussman):
Mark the read-only parts of the memcg interface const, from folio and
lruvec accessors to counters and swap helpers. Most of this is
mechanical, but it makes the contracts clearer and lets the compiler
catch accidental writes.
- "mm/damon/vaddr: support {prep,apply}_probes" (SJ Park):
Support the new prepare/apply probe operations in DAMON's
virtual-address backend. This brings vaddr monitoring into line with
the probe infrastructure and makes the added probe types useful there
too.
- "mm/mglru: clean up folio counters and flag usage" (Kairui Song):
Simplify MGLRU's folio counters and flag handling. Remove redundant
accounting paths and make the state transitions easier to follow
without changing the intended reclaim policy.
- "arch, mm/execmem: resolve confusion about set_direct_map_valid_noflush()"
(Mike Rapoport (Microsoft)):
Clarify and straighten out the set_direct_map_valid_noflush()
interface across architectures and execmem. Make the requested
mapping changes and the callers' expectations agree, rather than
relying on subtly different architecture behavior.
- "mm: zswap: free cold writeback folios promptly" (Alexandre Ghiti):
Free zswap writeback folios as soon as their disk write completes.
They are cold temporary buffers, so putting them on the LRU only
makes reclaim rediscover them later. Extend swap-cache dropbehind and
let zswap keep these folios off the LRU altogether.
- "mm: gup: cleanup gup_fast call chain" (Aristeu Rozanski):
Clean up the GUP-fast call chain and simplify how the fast-path
helpers pass their arguments and results around. Keep the page-pin
behavior the same while making the call sequence easier to maintain.
- "mm: optimize zone-device memmap initialization" (Li Zhe):
Speed up initialization of zone-device struct pages. Avoid redundant
work when setting up large device-memory ranges, where touching every
descriptor can get expensive.
- "mm/zswap: shrink zswap_entry via a pool id" (Jianyue Wu):
Reduce the size of zswap_entry by storing a compact pool identifier
instead of a full pointer. Keep the pool lookup and lifetime handling
correct while saving per-entry metadata.
- "mm/damon: support access monitoring of hugetlb-backed memory"
(Krishna Iyer):
Let DAMON monitor hugetlb-backed memory too. Extend the relevant
access checks and add coverage so those mappings no longer fall
through a hole in the monitoring machinery.
- "mm/execmem: fixes and cleanups for the ROX cache" (Mike Rapoport):
Tidy execmem's read-only-executable cache and fix its handling of the
awkward allocation and release cases. The aim is to make the cache's
ownership and permission transitions more predictable.
- "zsmallc: remove old object read API" (Sergey Senozhatsky):
Drop zsmalloc's old object-read API and move its remaining users to
the supported access mechanism. This removes a duplicate interface
which we no longer need.
- "mm/mempolicy: stop copying state in the interleave paths" (Gregory
Price):
Stop copying mempolicy state in the interleave paths when a reference
to the existing policy will do. This avoids extra work and makes the
ownership rules less obscure.
- "mm/mglru: speed up inc_min_seq() and fix cold/hot inversions" (Barry
Song):
Make MGLRU's generation advancement cheaper and fix cases where cold
and hot folios end up in the wrong order. Adjust the counter and list
handling so reclaim doesn't keep passing over the better eviction
candidates.
- "mm: Fix MF_DELAYED handling on memory failure" (Lisa Wang):
Treat MF_DELAYED as a partially completed memory-failure operation,
not an outright failure. Propagate that result correctly through
shmem and the generic handler, fix the extra-reference accounting,
and add tests for the resulting SIGBUS behavior.
- "tools/mm/page_owner_sort: fix --sort, add module filter, improve
usage" (Ye Liu):
Fix page_owner_sort's --sort handling, add module-based filtering and
make the usage output more helpful. This makes the tool less
frustrating when tracking down who is holding on to pages.
- "mm/damon: move damos filter range arguments validation to core" (SJ
Park):
Move DAMOS filter range validation into the core, where all callers
can share it. Also close the sysfs read-twice races which could pass
inconsistent ranges, and add tests for invalid input.
- "mm/damon: misc cleanups" (Zenghui Yu):
Clean up a collection of small DAMON rough edges in the core,
interfaces and tests. No large behavior change here, just simpler
code and fewer opportunities for confusion.
- "mm/damon: cleanup code, add test cases, and update guidances in
docs" (SJ Park):
Clean up DAMON's core and interfaces, add missing test cases and
bring the documentation into line with the code. These changes should
make the newer facilities easier to understand and maintain.
- "mm/damon: introduce hugepage_size probe filter" (SJ Park):
Add a DAMON probe filter for hugepage size. Let users select a range
of folio sizes through sysfs, validate the range and document the new
interface, so monitoring can concentrate on memory backed by the
desired hugepage sizes.
- "selftests/mm: pagemap_ioctl test fixes and cleanups" (Zenghui Yu):
Fix some pagemap ioctl test assumptions and clean up their setup and
reporting. Make failures point to the operation that went wrong
rather than to test harness bookkeeping.
- "mm: avoid large folio splits when swap is unavailable" (Johannes
Weiner):
Avoid splitting large folios merely to attempt swap when no swap
space is available. There is little point paying for an expensive
split when reclaim cannot actually swap the resulting pages out.
- "mm: workingset: fix the shadow node budget under MGLRU" (Hui Zhu):
Fix the workingset shadow-node budget with MGLRU enabled. Keep the
shadow entries within the intended limits so refault tracking does
not quietly consume more metadata than it should.
- "selftests/mm: TAP output and global-state fixes" (Song Hu):
Fix selftests which produce misleading TAP output or fail to restore
global settings after a run. A test ought to leave the system as it
found it, particularly when a whole suite follows behind.
- "mm: remove page_swap_entry()" (Tal Zussman):
Remove page_swap_entry() and convert its remaining users to the folio
and swap-entry helpers. Lose an old page-level interface and make the
swap paths a little more consistent.
- "mm: refactor zonelist constructors and iterators" (Gregory Price):
Refactor the zonelist construction and walk helpers to reduce
duplicated logic. Keep the allocation ordering rules intact while
making it clearer how zones are selected.
- "mm: kmemleak: batch the struct page scan" (Breno Leitao):
Scan adjacent struct pages in batches instead of taking kmemleak_lock
once for every single page. This preserves scan coverage and the
lock-hold bound, while cutting overhead substantially on debug
kernels.
- "mm/damon: misc improvements in tests and documents" (Zenghui Yu):
Fix some DAMON selftests which leave kdamond running or fail under
Python safe-path mode, and improve the KUnit coverage and
documentation. Nothing especially glamorous, but these are worth
doing.
- "mm/damon: introduce probe_hits_wsum DAMOS core filter" (SJ Park):
Add a DAMOS core filter using weighted probe-hit counts. This gives
schemes another way to select regions based on what the monitoring
probes observed.
- "mm/mglru: fix ineffective memory protection for non-kswapd reclaim"
(Ridong Chen):
Fix MGLRU's memory protection handling for reclaim outside kswapd.
The protection settings weren't having the intended effect in these
paths, leaving protected memory more exposed than requested.
- "mm/damon: improve readability, clarity and test coverage" (SJ Park):
Simplify a handful of DAMON core helpers, clarify their behavior and
expand test coverage. There are no intended userspace-visible changes
in this batch.
- "mm: replace PF_KCOMPACTD/PF_KSWAPD with kthread_func()" (Kefeng
Wang):
Stop identifying reclaim and compaction workers through the PF_KSWAPD
and PF_KCOMPACTD task flags. Use their kthread functions instead and
remove the redundant flag plumbing.
- "mm/hugetlb: fix surplus accounting and availability checks during
demotion" (Longlong Xia):
Fix HugeTLB surplus accounting and availability checks when demoting
huge pages. Keep the counters and reservation decisions consistent as
one huge page turns into several smaller ones.
- "mm/damon: add kunit tests for probe_hits handling and probe params
validation" (Jason Angelov):
Add KUnit tests for DAMON probe-hit handling and invalid probe
parameters. These cover edge cases that were too easy to miss in
ordinary monitoring tests.
- "mm/damon: fix misc bugs in kunit, quota goals and sysfs refresh_ms"
(SJ Park):
Fix a few DAMON bugs in KUnit tests, quota-goal handling and the
sysfs refresh interval. Small fixes, but the incorrect results and
control behavior were real.
- "mm: zswap: optimize zswap invalidate and store" (Kefeng Wang):
Simplify zswap's invalidate and store paths to avoid avoidable
lookups and work. Keep the entry lifetime rules intact while making
those frequent operations cheaper.
- "mm: replace custom ratelimiting logic" (Pedro Falcato):
Replace hand-rolled MM rate limiting with the common kernel helpers.
There is no need to maintain another local version of the same
mechanism.
- "mm/vmalloc: minor cleanups" (Ye Liu):
Tidy some vmalloc initialization and reporting code, and pull
duplicated vmap-area insertion work into a helper. No functional
changes are intended.
- "mm/mglru: clean up isolate_folios for readability and clarity"
(Ridong Chen):
Clean up MGLRU's isolate_folios() so the decisions are easier to read
and verify. Keep reclaim behavior unchanged while removing
unnecessary twists in the control flow.
- "Catch automatic storage in IDA and Maple Tree definitions" (Yury
Norov):
Catch IDA and maple-tree definitions placed in automatic storage
where the lifetime rules are wrong or easy to get wrong. Add checks
so such mistakes are harder to slip through unnoticed.
- "mm, swap: some random fixes and cleanups" (Kemeng Shi):
Fix and simplify a few unrelated swap paths, removing redundant work
and tidying up error handling. A small collection of things which
were better fixed than left lying around.
- "mm/page_io: folio conversion cleanups" (Tal Zussman):
Finish some page-to-folio conversions in swap I/O, removing obsolete
wrappers and using folio operations consistently. The I/O behavior is
intended to remain the same.
- "mm/swap: skip empty clusters in the swapoff scan" (Youngjun Park):
Skip empty swap clusters during swapoff instead of walking slots
which have nothing to release. This avoids pointless work on sparsely
used swap devices.
- "mm: trace: decode architecture-specific VMA flags" (Meijing Zhao):
Teach the VMA trace output to decode architecture-specific flags,
rather than leaving them as unexplained bits. That should make
tracing a good deal more useful when debugging unusual mappings.
- "mm, swap: don't spin on a bad swap entry" (Breno Leitao):
Stop repeatedly retrying a swap entry which is already known to be
bad. Make the error path terminate cleanly instead of wasting CPU
chasing an entry that cannot be used.
- "mm/page_isolation: fix UBSAN shift-out-of-bounds in
isolate_single_pageblock" (Qi Xi):
Fix an out-of-range shift in isolate_single_pageblock() and tighten
its associated boundary handling. UBSAN found the issue; the result
should be more robust pageblock isolation.
- "mm: khugepaged: fix tracepoint UAF" (Vernon Yang):
Fix a use-after-free in khugepaged tracepoint handling. Make sure the
information recorded by tracing stays valid for as long as the trace
event needs it.
- "mm/damon: fix DAMOS bugs in core, paddr and vaddr" (SJ Park):
Fix several DAMOS problems across the core and physical- and
virtual-address backends. The changes close error cases and bring the
implementations back into agreement.
- "mm/hugetlb_cgroup: move the per-node usage along with the folio"
(Hongfu Li):
Move HugeTLB per-node usage accounting when folios migrate between
nodes or are reparented to another cgroup. Otherwise numa_stat can
retain stale charges and even underflow when the folio is freed.
- "docs/core-api: memory-allocation: add k[mz]alloc_obj() and clarify
kmalloc" (Mike Rapoport):
Document the typed k[mz]alloc_obj() allocation helpers and clear up
some kmalloc guidance. Make it easier for callers to choose the right
interface.
- "selftests/mm: Validate selections and scope memfd_secret setup"
(Tianyi Chen):
Check selftest selections before running and confine memfd_secret
setup to the cases that actually need it. Avoid confusing failures
caused by the test harness itself.
- "mm/damon: move zero damos quota target_value handling to the core
layer" (SJ Park):
Handle a zero DAMOS quota goal target in the core rather than making
each user of the interface invent its own rule. Keep quota decisions
consistent across callers.
- "mm/damon: Introduce a huge page collapsing mechanism using auto
tuning" (Asier Gutierrez):
Add an auto-tuned DAMON mechanism for collapsing huge pages. Use
monitoring feedback to decide when collapse is worthwhile rather than
forcing one fixed policy onto every workload.
- "kmemleak: fix stale documentation and raise the verbose default"
(Breno Leitao):
Bring the kmemleak documentation up to date and require a third
confirming scan before verbose kernels print a suspected leak. The
extra scan helps suppress transient false positives in noisy debug
builds.
- "mm/memory: improve insert_pages() error handling" (Avi Weiss):
Tighten insert_pages() error handling so partial failures are
reported and cleaned up consistently. The caller should not have to
guess how far the operation got.
- "mm/damon: allow NULL or unstarted damon_ctx parameter for
damon_call()" (SJ Park):
Make damon_call() handle NULL and not-yet-started contexts safely.
Simplify the rules for callers and avoid an indefinite wait on an
invalid state.
- "mm/damon: introduce pgidle_set probe filter type" (SJ Park):
Add a pgidle_set DAMON probe filter, giving monitoring users another
way to select pages by their idle-tracking state. Wire it through the
filter interfaces and tests.
- "mm/damon/core: remove unused helper functions" (Cheng-Han Wu):
Remove DAMON core helpers which no longer have callers. Keep the API
surface smaller rather than retaining dead code just in case.
- "mm: stop calling pmd_folio() on special PMDs" (Gregory Price):
Avoid calling pmd_folio() on special PMD mappings that have no struct
page. The old assumption could fault in procfs walkers; use the
normal-folio checks and handle those mappings properly.
- "mm: remove three unused helpers from mm.h" (Tal Zussman):
Remove three unused helpers from mm.h. Fewer obsolete interfaces for
the next person to stumble over.
- "mm/damon: improvements in efficiency, error handling, documents"
(Liew Rui Yan):
Skip needless DAMOS quota work once the quota is full, propagate a
missing sysfs error and tidy a couple of comments. The ignored error
could make a monitoring-start request appear successful when it
wasn't.
- "docs/mm/damon/design: add explanation of nr_snapshots" (Liew Rui
Yan):
Explain DAMON's nr_snapshots accounting in the design documentation
and straighten out the associated terminology. Make it clearer what
users should expect from that counter.
- "selftests/cgroup: fixes for test_zswap on single core VM" (Wilson
Felipe Pereira):
Fix two test_zswap failures on single-CPU VMs. Wait for the exiting
child's cgroup to become unpopulated before reconfiguring it, and
avoid another test assumption which breaks under constrained
scheduling.
- "docs/ksm: fix advisor documentation and comment" (Jinjiang Tu):
Correct the KSM advisor documentation and a misleading code comment.
Keep the description aligned with how the advisor actually works.
- "Fix bugs in HugeTLB allocation when mem_cgroup_charge_hugetlb()
fails" (Ackerley Tng):
Fix HugeTLB allocation cleanup when the memcg charge fails. Make sure
failure exits undo what was allocated rather than leaving stale
accounting or resources behind.
- "mm, memcg: fix memory.peak reset clobbering other fds' watermark"
(Ridong Chen):
Fix memory.peak reset handling so resetting one file descriptor
doesn't overwrite the watermark kept for another. Keep those per-open
measurements independent as intended.
- "mm: reject zone device folios in more folio walkers" (Gregory
Price):
Reject zone-device folios in page walkers that cannot safely handle
them. Extend the existing checks rather than assuming every folio has
ordinary system-memory backing.
- "percpu: remove code with no effect" (Sang-Heon Jeon):
Remove a few pieces of percpu code which no longer do anything. There
is no reason to keep maintaining dead paths.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"This includes a significant number of low-priority fixes - especially
in the NIC drivers area - that we deferred from the last few RCs in
the previous cycle, which can't be easily outlined in the synopsis
below.
Core & protocols:
- Continue the work on removing rtnl_lock dependencies:
- per-netns ARP and ND neighbour tables, with the default settings
now configurable per netns (inheritance from init_net is
controlled by the new net.core.neigh_inherit_init_net sysctl)
- RCU-protected configuration and rtnl_lock-less fill_info() for
hsr, netkit, sit, vlan and vxlan devices
- per-netns device unregistration for ip tunnel and gre devices
- use the netdev instance lock instead of rtnl_lock when reading
speed and duplex via sysfs
- batch the flushing of uncached routes at device unregistration
time, relieving rtnl_lock contention on netns dismantle.
- Add hardware pacing offload support, admin-controlled via a new
rtnetlink attribute, with sch_fq integration (implemented in idpf).
- Re-segment BIG TCP GSO packets into GSO packets fitting the egress
device limits instead of plain MSS-sized segments, improving
throughput for mixed BIG TCP / non-BIG TCP paths by up to 70%.
- Generate RSS keys that spread flows over all the RX queues; the
previous random keys could leave some queues unused.
- Optimize the bridge VLAN forwarding paths: cache the port-VLAN in
fdb entries and consider only VLAN members when flooding, for ~10%
more Mpps in the fdb forwarding path.
- A few TCP/IP performance improvements aimed at efficient cache
usage and reducing contention.
- Add the TCP ROCCET congestion control, a CUBIC variant aimed at
avoiding bufferbloat in cellular networks.
- Continue the conversion of getsockopt callbacks to sockopt_t.
- Add an ethtool command to list the front-facing ports of an
interface, including SFP cages and modules, using the phy_port
representation.
- Enable BIG TCP support for bareudp tunnels.
- Remove the IPV6_ADDRFORM socket option and disallow buggy TCP state
transitions (listen() + shutdown() + connect() and connect() +
connect(AF_UNSPEC) + listen()).
- Remove most BUG_ON()s from core packet processing, replacing them
with error paths.
Wireless:
- Latency improvements, including lockless station get/dump and
beacon updates, plus RTNL reduction and locking cleanups.
- Infrastructure for non-station TX/RX with MLO.
- NAN (Wi-Fi Aware) Instant Communication support and other NAN
improvements.
- Control frame Integrity Protocol (CIP) and protected TWT support.
- Improvements for AP regulatory checks.
Netfilter:
- Disable br_netfilter in user namespaces and schedule it for removal
in 2027.
- Restrict the raw table in nft_compat to the specific family, hook
and priority.
- Prepare the flowtable for mixed IPv4-over-IPv6 tunneling (and vice
versa).
- Use GFP_KERNEL_ACCOUNT for most netfilter allocations, for better
integration with memcg.
- Allow discovering conntrack zone filtering support in ctnetlink
dumps, and fix nfnetlink_hook handling of large dumps.
Deletions:
- Move the LLC type 2 sockets out of tree. There are no known users
and the code attracts a never-ending stream of LLM-driven fixes.
Device drivers:
- New drivers:
- Meta Platforms NIC (mpnic), the second-generation NIC from Meta
- initial skeleton of the Nebula-matrix NICs driver (nbl)
- X-Powers AC200/AC300 Fast Ethernet PHYs
- Ethernet high-speed NICs:
- Intel:

"Quite a lot of work in the SPI subsystem this time around, almost all
in drivers rather than the core.
As well as the general cleanup/fix work we're seeing over most of the
kernel there's been some substantial performance work to two existing
drivers and support for a number of new devices including a couple of
new drivers. There was also a big overhaul of the spidev_test utility
from the Pengutronix people.
- Improvements for spidev_test to cover additional use cases, plus be
a bit easier to use.
- Substantial performance work in both DesignWare and Tegra210 QSPI
drivers, making their interrupt handling more efficient to drive up
hardware utilisation.
- Documentation clarifications.
- Fixes for some runtime PM and error handling issues.

Pull power management updates from Rafael Wysocki:
"This time, the most visible part are the ACPI CPPC updates from
Christian Loehle, including CPPC cpufreq driver changes, even though
updates of cpufreq drivers proper are still the largest topic group.
However, the updates of cpufreq drivers depend on the ACPI CPPC
updates, so they should really be counted together and that is well
over 1/2 of the total commit count.
Interestingly enough, almost all of the updates included here are
fixes or cleanups, with some new feature support in the amd-pstate
cpufreq driver and IPQ9650 support in the qcom-nvmem cpufreq driver.
The runtime PM documentation improvements from Brian Norris can also
be mostly regarded as fixes, but a new kunit test goes along with
them.
Specifics:
- Fix multiple issues related to input validation, synchronization,
access safety, memory layout and register field validation, and
error handling in the ACPI CPPC library (Christian Loehle and Sumit
Gupta)
- Select the frequency-invariance callback per CPU in the CPPC
cpufreq driver and create the FIE worker before enabling PCC
callbacks in it to avoid queueing work through a missing worker and
dereferencing a NULL pointer (Christian Loehle)
- Update the CPPC cpufreq driver entry in MAINTAINERS and add a new
entry for the ACPI CPPC library (Christian Loehle)
- Minor fixes in various cpufreq drivers (Alexander Koskovich, Daniel
Schwierzeck, Frank Zhang, Haotian Zhang, Kathiravan Thirumoorthy,
Sumeet Pawnikar, and Xueqin Luo)
- Fix wrong behaviors on multi-node servers in the Loongson cpufreq
driver (Huacai Chen)
- Reject NULL from cpufreq_cpu_get() in the Rust code (Mehmet
Koseoglu)
- Add suspend OPP to mediatek cpufreq driver and DT (Ryan Brue)
- Fixups for a few bugs identified by Sashiko in the amd-pstate
cpufreq driver (Mario Limoncielloi, Wentao Guan)
- Initial support for maximum frequency capacity handling on Zen6
client in amd-pstate (Mario Limonciello)
- Fix for amd-pstate-ut with 'Requested CPU Min frequency' BIOS
option (K Prateek Nayak)
- New Zen6 tuning values for EPP in amd-pstate (Mario Limonciello,
Vishal Badole)
- amd-pstate documentation fix (Karl Mehltretter)
- Restrict deferred downscaling to low load for shared policies in
the conservative cpufreq governor to avoid undesirable CPU
frequency reduction in some cases (Shengming Hu)
- Serialize sugov_start() against rate limit updates in the schedutil
cpufreq governor to avoid using a stale rate limit value (Hui Su)
- Prevent cpuidle governors menu and teo from returning idle state 0
after it has been disabled (Xueqin Luo)
- Replace min_t() with the better alternatives in the intel_idle
driver and make it use 2-argument strscpy() (Andy Shevchenko)
- Fix two repeated phrase instances in cpuidle (Hemanth Selam,
Syazwina Fazrul)
- Add rugged Panther Lake support to the intel_rapl power capping
driver and make it use %pe for printing error pointers (Srinivas
Pandruvada and Sumeet Pawnikar)
- Update and improve runtime PM documentation and add a kunit test
for supplier idle/suspend (Brian Norris)
- Add a pm_runtime_dont_use_autosuspend() call to pm_runtime_reinit()
to ensure autosuspend disabling on driver teardown (Joshua Crofts)
- Ignore page-zero RAM in E820 checksum during hibernation on x86 to
avoid rejecting images created after kexec() (Matthias Goergens)
- Add resume event mapping for PMSG_POWEROFF to the PM core to allow
it to carry out device shutdown in the future (Mario Limonciello)
- Add DPM watchdog to prepare/late/early/noirq/complete phases of
device suspend and resume (Mayank Rungta)
- Update swsusp.txt references to swsusp.rst in hibernation
documentation (Li Jun)
- Fix use-after-free of perf domain in netlink doit handlers for
energy models (Fan Wu)
- Add synchronize_rcu() back to cpu_pm_unregister_notifier() after it
was removed inadvertently in previous development cycles to avoid
use-after-free (Bradley Morgan)
- Unregister CPU PM notifier outside the timer lock in the
timer-ti-dm clocksource driver (Bradley Morgan)
- Fix typo "sucessfully" in a comment in pm_clk_add_clk() kerneldoc
comment and typo "hierachy" in a comment in pm-graph (Hemanth
Selam)
- Fix the return value in dev_pm_opp_get_of_node() kernel-doc (Karl
Mehltretter)"

Userspace has no way to know whether the kernel supports the
resizable_tail_secno mount option before mounting. Passing it to a
kernel without the support fails the mount with -EINVAL, and checking
/sys/fs/f2fs/<disk>/pinned_area_max_secno requires an f2fs instance
to be mounted already.
Export /sys/fs/f2fs/features/resizable_tail so that userspace can check
the support before formatting or mounting a filesystem that relies on
resizable_tail_secno, e.g. a filesystem whose tail is going to be shrunk

The Lenovo Yoga Slim 7x Gen 11 (Qualcomm glymur / Snapdragon X2 Elite)
carries a Compal EF06 embedded controller on I2C at address 0x70. The
platform firmware describes it as an ACPI GenericSerialBus region, but the
machine boots from device tree, so nothing otherwise talks to it.
Commands are exchanged with two raw I2C block transfers: a 7 byte write to
register 0x02 carrying the command and up to six arguments, then a 6 byte
read of register 0x01 for the result, with a short delay in between before
the result register is valid. The EC offers no way to match a result to
its command; the delay is the one the vendor ACPI code uses.
Expose what the EC offers that the rest of the kernel does not already
provide:
- the board thermistors that report a value at probe, five on this
machine, as hwmon temperature channels. These are charger, CPU
voltage regulator, 5 V rail and ambient sensors, not die sensors, and
read considerably cooler than tsens
- CPU fan speed in RPM
- the keyboard backlight as an LED, off/low/high
- Fn-lock as a read/write sysfs attribute, matching the ideapad-laptop
interface. The EC reports Fn+Esc as an event but keeps no state of its
own, so the driver owns the bit and toggles it on the key
- the mic-mute and airplane-mode keys as KEY_MICMUTE and KEY_RFKILL.
These reach the host only as EC events; they are not on the keyboard's
HID interface and have no GPIO of their own
The EC signals pending events on a dedicated line, and keeps pulsing it
until they are read - so the queue must be drained completely on every
interrupt, including codes this driver ignores. Leaving one behind makes
the controller pulse indefinitely.
Fan speed is reported but not controlled. The EC accepts a manual setpoint,
however it enforces no thermal floor over it: with the fan pinned at
roughly 2000 RPM under full load the SoC rose from 69 to 91 degrees in 30
seconds without the EC ever overriding. Exposing pwm1_enable or fan1_target
would therefore let userspace overheat the machine, so neither is
implemented.
Note this is the Gen 11 machine specifically. Its EC differs from the
Qualcomm reference EC that the reference designs place at address 0x76,
which is not populated here, and so EC_QCOM_HAMOA does not drive it.

Commit 3de6b8094115 ("f2fs: Run f2fs_write_end_io() asynchronously")
introduced max_atc_write_bio_size to offload write bio completion to a
workqueue when f2fs_write_end_io() is called in atomic context.
However, using the bio byte size (bi_iter.bi_size) as the threshold has
limitations once large folios or multi-page bvecs are involved:
1. In f2fs_write_end_bio(), execution time is dominated by the
completion loop (bio_for_each_folio_all() for pagecache folios,
or while(entry) for cached metadata blocks), where per-entry
locking, status clearing, sanity checks, and writeback end are
performed. The CPU latency in atomic context scales with the number
of entries in the bio, not its byte size.
2. For large folios, a large bio (e.g. 1MB comprised of single large
folios) only iterates a few times through the loop. Throttling solely
by max_atc_write_bio_size unnecessarily offloads such low-latency
bios to the workqueue, adding context-switch overhead.
3. Conversely, relying on bio->bi_vcnt is insufficient because the block
layer (bvec_try_merge_page) merges physically consecutive pages/folios
into the same bio_vec segment. Thus, a bio with bi_vcnt == 1 could
still contain multiple entries and iterate many times in end_io.
To address this, track the exact number of entries (folios or cached
blocks) queued to the write bio via entry_cnt in struct f2fs_bio, and
introduce a sysfs attribute max_atc_write_bio_entry_cnt. This enables
precise control over atomic context latency without penalizing large
folios.

This patch introduces cache_wb_dirty_threshold and cache_wb_total_threshold
sysfs nodes under /sys/fs/f2fs/<disk>/, and wakes up the f2fs_writeback
kthread when dirty meta/node caches exceed cache_wb_dirty_threshold and
total cached entries exceed cache_wb_total_threshold; a zero threshold
disables the corresponding check. By default, cache_wb_dirty_threshold is
8192 and cache_wb_total_threshold is 0.
If both thresholds are zero, f2fs_writeback only runs periodically, unless
checkpoint is disabled, as nothing else will flush dirty caches then.
f2fs_writeback won't be woken up unless there are enough dirty caches for
f2fs_write_{meta,node}_caches() to gather. And if thresholds are exceeded
but one round fails to write any caches, e.g. due to cp_error, freezing,
frozen fs, or lock contention, threshold based wakeup is throttled until
a later round makes progress, in order to avoid busy-looping. To detect
progress, introduce a new parameter for f2fs_write_{meta,node}_caches()
and f2fs_writeback_node_caches() to return the number of caches submitted
for writeback.
Thanks Daeho and Wenjie for help and suggestion on this patch.

Manivannan writes:
MHI Host
--------
- Add a host-side loopback client driver that binds to the standard MHI
LOOPBACK channel and exposes a sysfs interface for data path testing. The
interface lets users configure the TRE buffer size and count, trigger a
loopback test, and read back the result to validate the MHI data path
between host and endpoint.
- Add the IP_CTRL channel (18/19) to the Sierra EM919x/EM929x channel
configuration. IP_CTRL is a standard Qualcomm MHI control channel that
carries the host serial control lines (DTR/RTS) to the modem, which the
host previously had no way to drive for these devices.
- Add the DUN uplink (32) and downlink (33) channels to the Qualcomm modem
channel configuration. These channels transport AT commands over MHI and
let userspace reach the modem AT interface through the MHI WWAN client
driver.
- Add support for the Quectel RM500Q-AE (SDX55) module. It provides MBIM
control on channels 12/13, not the QMI setup that the generic SDX55 entry
assumes, so QMI requests over the control channel were timing out. Add an
entry matched by its subsystem ID that reuses the Quectel MBIM channel
configuration, so no out-of-tree driver is needed.
- Fix a runtime PM usage count imbalance for no_m3 devices in the pci_generic
driver. Probe only dropped the reference taken by the PCI core when the
device supported both PME from D3hot and M3, while remove re-took it based
on PME capability alone. The count therefore crept up on every bind/unbind
cycle and could end up preventing runtime suspend. QDU100 is the only
affected device today.
- Convert the %pK pointer format specifier to %p. Pointers are hashed by
default now, so %pK is no longer needed to prevent address leaks, and %p
keeps the value available for debugging.
- Fix a spelling typo ("intented") in a comment.
MHI Endpoint
------------
- Add the mhi_ep_queue_buf() API for queuing raw buffers on downlink
transfers, for endpoint clients that do not use socket buffers. The
existing mhi_ep_queue_skb() is refactored to share a common internal
helper with the new API.
- Add an endpoint-side loopback client driver that binds to the LOOPBACK
channel and echoes received data back to the host. On a Linux-based
endpoint there is no modem firmware to provide the echo, so this driver
acts as the software echo partner for the host loopback driver and
completes the end-to-end MHI data path test.
- Pass IRQF_NO_AUTOEN to request_irq() for the doorbell IRQ instead of
setting IRQ_NOAUTOEN on the descriptor by hand. The manual flag was never
cleared on the error paths or at unregister, so it leaked onto the
descriptor after the IRQ was freed.

It turns out that some models require the lightbar to be activated
in order to display the rainbow animation, so users have to access
both the "rainbow_animation" sysfs attribute and the LED sysfs
interface when enabling the rainbow animation. This can cause short
glitches when the lightbar was previously disabled.
Fix this by replacing the sysfs attribute with a custom LED trigger
called "uniwill-rainbow". Selecting this trigger will atomically
activate the lightbar and enable the rainbow animation mode. This
can potentially break userspace applications using the old sysfs
attribute, but so far no such application is known to exist (yet).

The MHI specification defines a LOOPBACK channel. The endpoint firmware
echoes back whatever the host sends on this channel. Without a host-side
driver, there is no way to exercise this channel to validate MHI data path
integrity between host and endpoint.
Add a host-side loopback driver that binds to the LOOPBACK channel and
expose a sysfs interface for data path testing. The sysfs interface allows
users to configure TRE buffer size and count, trigger a loopback test, and
read the result.
The new sysfs ABI is documented under Documentation/ABI/testing/, not
stable/, since this is a new interface without established API
guarantees yet. It is unrelated to the existing stable MHI sysfs ABI
documented in Documentation/ABI/stable/sysfs-bus-mhi, despite both
being covered by the same MAINTAINERS entry.

Currently, the "label" and "acpi_index" attributes are created whenever the
_DSM function 0 bitmap advertises the Device Name function, without
evaluating that function. The documented ABI states that each attribute is
created only if the firmware has given a name or an instance number to the
PCI device.
The bitmap says nothing about the object the function returns. Firmware
that advertises the function but returns an object that cannot be parsed
therefore produces attributes that exist and fail every read, as in the
report below.
Evaluate the Device Name _DSM when deciding attribute visibility and create
each attribute only when the element it exports has a type the read path
accepts, mirroring the checks performed at read time. The SMBIOS attribute
group already follows this pattern by performing the DMI lookup in its
is_visible() callback. The read side checks remain in place since the two
evaluations happen at different times.
This restores the behaviour from before commit 2fc59fe2ecdc ("PCI /
pci-label: treat PCI label with index 0 as valid label"), which switched
visibility from evaluating the function to checking only the function 0
bitmap. The check is now made for each attribute, not once for both.

The documentation for the input current and voltage limits recommends
using those properties for problems that can be solved using a power
limit. This contradicts the recommendation to prefer input_power_limit
for such cases.
Similarly, the input_power_limit documentation recommends using the
current or voltage limits for problems that can be solved with a power
limit, which conveys the opposite of the intended meaning.
Fix the wording to clarify that input_power_limit should be preferred
whenever a power limit can address the problem, while current or
voltage limits should be used when it cannot.

This would help
- Users to quickly check which CPUs are marked as preferred.
- Userspace daemons such as irqbalance to use this mask to
route irqs into preferred CPUs.
For example:
cat /sys/devices/system/cpu/online

cat /sys/devices/system/cpu/preferred
0-599 <<< Implies 0-599 are preferred for workloads and 600-719
